Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00358 - 0.02025), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.43 se; based on food items.

Generation time: 2.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (tmax= 7; K= 0.02;).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
